iron (Fe), chemical element, metal of Group 8 (VIIIb) of the periodic table, the most-used and cheapest metal.
What is germanium metal?
germanium. germanium (Ge), a chemical element between silicon and tin in Group 14 (IVa) of the periodic table, a silvery-gray metalloid, intermediate in properties between the metals and the nonmetals.
Does GE possess metallic properties?
Germanium is a hard, grayish-white element, has a metallic luster but is brittle like glass. It is classified as a metalloid having the same crystal structure as diamond.
Why is GE a metalloid?
As a metalloid, germanium has both metal and non-metal qualities. It also is a semiconductor, which means it has electrical conductivity between an insulator and a conductor. This characteristic has led to it being used in electronics.
What type of solid is GE?
Germanium is a chemical element with symbol Ge and atomic number 32. Classified as a metalloid, Germanium is a solid at room temperature.
What is metallic and non-metallic?
Metallic Minerals are minerals in which metal elements are present in their raw form. Non-metallic minerals do not contain any metal substances in them. When metallic minerals are melted a new product is formed. In the case of non-metallic minerals, you don’t get any new product after such a process.
Which is a metallic mineral?
These deposits can consist of a variety of metallic minerals containing valuable metals that are used in various aspects of our daily lives such as: nickel (pentlandite) copper (chalcopyrite) zinc (sphalerite) lead (galena)
What germanium is used for?
The largest use of germanium is in the semiconductor industry. When doped with small amounts of arsenic, gallium, indium, antimony or phosphorus, germanium is used to make transistors for use in electronic devices. Germanium is also used to create alloys and as a phosphor in fluorescent lamps.
Is germanium bracelet safe?
Some people believe that germanium can help treat a variety of conditions. But germanium has been linked to serious side effects, including the risk of kidney damage and death.
Is GE shiny or dull?
Characteristics and Properties
Under standard conditions Germanium is a hard, shiny, silvery-gray solid that is very brittle. It is one of the few elements that expands when it freezes or turns solid. As a metalloid, germanium has both metal and non-metal qualities.
What are the properties of germanium?
Pure germanium is a hard, lustrous, gray-white, brittle metalloid. It has a diamondlike crystalline structure and it is similar in chemical and physical properties to silicon. Germanium is stable in air and water, and is unaffected by alkalis and acids, except nitric acid.
Is germanium a heavy metal?
Environmental effects of Germanium
Physical dangers: The gas is heavier than air and may travel along the ground; distant ignition possible. As a heavy metal it is considered to have some negative impact in aquatic ecosystems.
What are metallic solids?
5 days ago
Metallic solids are composed of metal cations held together by a delocalized “sea” of valence electrons. Because their electrons are mobile, metallic solids are good conductors of heat and electricity.
What is metallic crystal?
A crystalline solid in which the atoms are held together by metallic bonds. Metallic crystals are found in some interstitial compounds as well as in metals and alloys. From: metallic crystal in A Dictionary of Chemistry » Subjects: Science and technology — Chemistry.
What are non-metallic elements?
Hydrogen, carbon, nitrogen, oxygen, phosphorus, arsenic and selenium are the non-metallic elements in the periodic table.
What is metallic material?
Metallic materials are inorganic substances, usually combinations of metallic elements, such as iron, titanium, aluminum, and gold, which may also contain small amounts of non-metallic elements, such as carbon, nitrogen, and oxygen.
What is a metallic element?
What Is a Metal Element? By definition, a metal element is an element that form positive ions and has metallic bonds. Most elements on the periodic table are metals. Examples of metal elements include iron, copper, silver, mercury, lead, aluminum, gold, platinum, zinc, nickel and tin.
What are the two metallic minerals?
These deposits can consist of a variety of metallic minerals containing valuable metals that are used in various aspects of our daily lives such as:
- nickel (pentlandite)
- copper (chalcopyrite)
- zinc (sphalerite)
- lead (galena)
- gold (occurs as a native element or as a minor constituent within other minerals)
What are 3 common uses of germanium?
Germanium is used to manufacture rectifiers, transistors and weapons-sighting systems and used as a fluorescent material. Alloying agent. Germanium can also be used as a catalyst to produce plastics.
Is pure germanium toxic?
Similar to silicon and aluminium, naturally-occurring germanium compounds tend to be insoluble in water and thus have little oral toxicity.
Is germanium toxic to humans?
Germanium is not an essential element. Its acute toxicity is low. However, at least 31 reported human cases linked prolonged intake of germanium products with renal failure and even death. Signs of kidney dysfunction, kidney tubular degeneration, and germanium accumulation were observed.
What does germanium do to the body?
Inorganic (elemental) germanium is LIKELY UNSAFE. This includes certain compounds such as germanium oxide. There have been more than 30 reports of kidney failure and death linked with use of these forms of germanium. It builds up in the body and can damage vital organs such as the kidneys.
